Application filed November 16, 1915. Serial No. 61,833.

To all whom it may concern:

Be it known that I, JAMEs MEADE, a citizen of the United States,residing at Stoughton, in the county of Norfolk and State ofMassachusetts, have invented a new and useful Method of ProducingDoubled Fabrics, of which the following is a specification.

In the manufacture of doubled fabrics, or those consisting of two layersof material joined by an intermediate layer or layers of a waterproofsubstance, it has been found Very difiicult to produce satisfactorygoods when one of the layers of fabric is thin or loosely woven, as isthe case with mohairs employed" for automobile tops. Under the usualmethod of procedure the back and face layers of fabric are separatelycoated, partly allowed to dry, and then the two coated surfaces areforced together. The pressure necessary to effect proper adhesion is sogreat that the coating is often squeezed through the interstices of thethinner fabric and appears upon theface. If this does not occur, thepressure mats down the surface of the face fabric and destroys theoriginal mill-finish, considerably decreasing the value of the goods.The present invention brings about the junction of the layers by areadily pursued method without injuring the appearance of the product.

The accompanying drawing shows diagrammatically a single form ofapparatus by which my improved method may be carried out.

At 10 appears a supply-roll mounted, at one extremity of a suitableframe-work 11 and carrying the fabric F which is to furnish one layer ofthe doubled goods. From the supply-roll the fabric passes over thebed-roll 12- of a spreader S, said bed-roll being driven-at the desiredspeed from any suitable source of power. The preferably adjustablegage-knife 13 ofthe spreader coiiperates with the coating substanceindicated at M to distribute a thincoat over the upper face of thefabric. Upon leaving the spreader the now coated fabric is directed by adriven roll 14 about a heating coil 15, and then travels down aboutidler rolls 16 and again upwardly to the driven bed-roll 17 of a secondspreader S. The gage-knife 18 of the spreader S applies tothe coatedsurface of the fabric F a thin film of a quite fluid and highly adhesivesubstance M, say

one containing a considerable" amount of rubber. The thickness of thiscoating may be determined by the adjustment of the gage-knife 18. Beyondthe spreader S in the direction of advance of the material are standards19, in which are mounted vertically adjustable supports 20 carrying thebearing blocks 26 of a pressure-roll 27. These blocks are adjustablelongitudinally of the supports, and therefore the roll 27 is movabletoward and from the bed-roll 17 as Well as vertically.

The. fabric F, with its set or hardened coating applied at the spreaderS and its just applied and undried coating given by the spreader .S,travels under' 'the roll 27 and over a guide-roll 28 which is locatedquite close to the bed-roll 17 and in the same horizontal plane. 'From asupply-roll 29' the face-fabric F passes over and then beneath thepressure-roll-27,--which forces the a relatively light and yieldingpressure. The peculiar action-of this pressure-roll is due to the factthat there is no codperating r '80 pressure member beneath the goods,the roll --two layers of fabric together, thoughwith 27 acting upon therun between rolls 17 and28, sothat the goods are free to move from thesource of pressure, held against the roll 27 only by their own tension.This roll is adjusted asclosely as possible to the bed-roll 17 yetpermitting the desired yield of the goods, and therefore the coating ofthe substance M comes into contact with the face fabric F before itperceptibly dries and in a fluid and highly adhesive condition. Thisbeing the case, the light pressure of the roll 27 effectively smears anddisfaces of fabric and secures the proper adhesion. So thin isthe filmof the substance M and, 'so delicate the pressure, that there tributesitbetween the entire meeting suris nof-danger of its passing through theend of the machine by a guide-roll 31. This sets the coating of thesubstance M and completes the goods, which are received by the Windingroll 32, so rotated as to keep the material under proper tension.

1 I claim as my invention:

1. The method of producing doubled fabrics which consists in applying toa layer of fabric an extremely thin coating of a highly adhesivematerial, immediately after such application bringing into contact withthe adhesive coating a second layer of fabric, and pressing the twolayers together While they are movable from the source of pressure.

2. Th method of producing doubled fabrics which consists in applying toa layer of fabric a coating of Water-proof material, drying saidcoating, applying to such coating a film of highly adhesive material,immediately thereafter and before the adhesive perceptibly driesbringing into contact with the adhesive a second layer of fabric, andpressing the tWo layers lightly together While they are movable from thesource of pressure.
